PETROLEUM HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 331,161, dated November24, 1885, Application filed December 31, 1888. Serial No. 116,134. (Nomodel.)

To all whom, it may concern:

Be it known that I, ROBERT ScHULz, of the city of Dresden, in theKingdom of Saxony and German Empire, have invented certain new anduseful Improvements in Petroleum Heating Apparatus, of which thefollowing is a specification.

My invention relates to heating apparatuses wherein the volatilehydrocarbons are used in combination with steam for atomizing theburning fluid; and the nature of my invention consists in certain novelimprovements,whereby great economy of fuel is obtained, as will be fullyunderstood from the following description, when taken in connection withthe annexed drawings, in which Figure 1 is a vertical central section ofthe heater, and Fig. 2 a detail showing the register.

A designates the base of the heater, and B a cylinder mounted thereon,and provided with a door, I), and numerous perforations, b, for freelyadmitting air into it. Inside of the cylinder B is a lamp, 0; or,instead of a lamp, a gas-jet may be employed, the object of which 1s toheat a steam-generator, D, suspended from the roof of cylinder B, andprovided with a safety-valve, d, and also with a pipe, d leading out toa cock, d. With the pipe d is connected a pipe, 01 communicating with awaterreservoir, E, on top of a cylinder, F, which is mounted on thecylinder B, and provided with an outlet-flue, f, which may be made quitesmall. Surrounding the cylinder B is an annular chamber, G, forcontaining the burning fluid or fuel, which chamber is provided with afilling-aperture, g, properly closed. To this vessel 0 is applied apipe, g, provided with a regulatingcock, g, and ex tended horizontallyto a point just over the jet-tube d of the steam-generator D. I thusprovide the apparatus with means for supplying in a chamber, J, theburning-fluid and at the same time atomizing the same, as indicated inFig. 1. The wall surrounding chamber J is provided with a horizontalseries of apertures or air-inlets, j, and these apertures are providedexternally with an adjustable draftregister ring, by means of which theadmission of air into chamber J can be regulated as may be foundnecessary.

H designates a centrally-arranged cylindrical flue, the lower end ofwhich extends through the roof j of the chamber J, directly over the jetal and it may be made flaring, as shown in the drawings, or it may becontracted. The lightly-heated products of com bustion ascend to the topof the flue H, and then dive down between this flue and an externalconcentric cylinder, I, which depends from an oven, K, located near thetop of the cylinder F. From the bottom of the cylinder I the products ofcombustion ascend between it and cylinder F, and after circulating aboutthe oven K they escape through the flue f.

I am aware that it is not new inheating apparatuses to atomize fluidhydrocarbons by means of steam jets or ejectors, and therefore I lay nobroad claim thereto.

In a heating apparatus, the combination of two air-chambers providedwith valves, the oil-supply pipe, the air or steam pipe, the chimneyopening into the upper air-chamber, and the exit-fines formed by thecylinders D and E, substantially as described.

ROBERT SOHULZ.
